Eye defects can be corrected by surgery these days. One of the ways is LASIK which stands for laser-assisted in situ keratomileusis.

LASIK is a surgical alternative to wearing corrective eyeglasses or contact lenses. It was developed in 1990 and quickly became popular because of its greater precision and lower frequency of complications. With nearsighted people, the goal of LASIK is to flatten the too-steep cornea. With farsighted people, a steeper cornea is desired.

Younger people with mild nearsightedness and astigmatism are the best candidates for a good outcome. If you are considering LASIK eye surgery, your first step is to choose a good LASIK surgeon who can evaluate whether LASIK is right for you. Your eye surgeon will examine your eyes to determine their health, what kind of vision correction you need and how much corneal tissue removal is required. The doctor will also ask about any health conditions that may disqualify you altogether for LASIK surgery.

LASIK is an outpatient procedure. The LASIK surgeon uses a computer to adjust the laser for your particular prescription. You will be asked to look at a target light for a short time while the laser sends pulses of light to painlessly reshape your cornea. The actual LASIK surgery usually takes less than five minutes.

Before surgery, the patient's corneas are examined to determine their thickness. A topographer is used to measure their surface contour as well. Then, using the information, the surgeon calculates the amount and locations of corneal tissue to be removed during the operation. The operation itself is made by creating a thin flap on the eye, folding it to enable remodeling of the tissue underneath with laser. The flap is then repositioned and the eye is left to heal in the postoperative period.

LASIK is performed in three steps. The first step is to create a flap of corneal tissue. The second step is remodeling the cornea underneath the flap with the laser. Finally, the flap is repositioned. A corneal suction ring is applied to the eye, holding the eye in place. This step in the procedure can sometimes cause small blood vessels to burst, resulting in bleeding.

Although many people who have had LASIK believe they see better than they did with eyeglasses or contact lenses before surgery, not everyone has the same experience. The feedback given is as follows. After LASIK, one can expect the vision to be slightly better or about the same as it was with glasses. A small percentage of people may notice that their vision is not quite as good as it was before with glasses. However, the recipient should be able to drive safely and perform other routine daily tasks without needing glasses or contact lenses.

A few patients experience poor outcomes from LASIK surgical procedures. Those that did, report a significantly reduced quality of life because of vision problems. Generally, surveys determining patient satisfaction with LASIK have found most patients satisfied, with satisfaction range being 92-98 percent. As can be seen, LASIK is a therefore breakthrough in eye surgery to correct nearsightedness, farsightedness and astigmatism.

Answer
 
LASIK is a breakthrough for people who have eyesight problems. It is an outpatient procedure. The surgeon uses laser to painlessly reshape the cornea. Before surgery, the patient's corneas are examined. Then, the amount and locations of corneal tissue to be removed are measured. The operation is done in three steps. First, create a flap of corneal tissue. Second, remodeling the cornea underneath the flap with laser. Finally, the flap is repositioned. A corneal suction ring is applied to the eye, holding the eye in place. While this is going on, small blood vessels can burst, resulting in bleeding. Not everyone after LASIK has the same experience. Most have better vision than before. For some, their vision is not quite as good as it was before with glasses. (127 words)
